# Generic PII Anonymization

PII stands for Personal Identifiable Information. The defining aspect of PII data is that **you do not want the real values in your dataset to leak**. Typically, PII has a higher-level, semantic meaning and it may be possible to create other new values completely from scratch if you know the meaning.

![For example, names, phone numbers or addresses are all sensitive data that you do not want to leak.](https://2225246359-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FVGX92M819eIp0rMg5elc%2Fuploads%2F7BeWiaKbWB82wI52MpXd%2Frdt_transformers-glossary-generic-pii-anonymization_June%2002%202025.png?alt=media\&token=ea691704-b1a1-4b3c-ab54-0d859a62e142)
